Question

1) Dados os conjuntos A = { 2,3 }, B = { -3,1 } e C = { 0,2,5 }, determine:
a) A X B =
b) A X C =
c) B X A =
d) C X A =
e) B2 =

Answer 1

Resposta:

a) AxB={(-1,2),(-1,3},(0,2),(0,3),(1,2),(1,3),(2,2),(2,3)}

b) BxA={(2,-1),(3,-1),(2,0),(3,0),(2,1),(3,1),(2,2),(3,2)}

c) A^2={(-1,-1),(-1,0),(-1,1),(-1,2),(0,-1),(0,0),(0,1),(,2),(1,-1),(1,0),(1,1),(1,2),(2,-1),(2,0),(2,1),(2,1)}

d)B^2={(2,2),(2,3),(3,2),(3,2)}
